I am having the exact same issue and would like to know if you found a resolution, CAcreeks. I just purchased my C-Max and am going to be headed back to the dealership as this is within the guarantee, would still like to know if there is a fix.....
Describe your issue. Are you referring to the first post? I don't recall anyone else ever mentioning a message that says "see owner's manual." If this is the mssg, where is it displayed?
As far as the Sync message, it is normal to get a mssg that says something like "shutting down to save power" and then "performing routine maintenance".
If it is the "yellow wrench", you need the DTC. You can put the left screen in Engineering Test Mode (see post 17) and scroll through the screens to read the codes (see attachment). We can likely now "translate" what the codes say.
